Scaley Face Mites

Share This!

Birds are occasionally infected with a mite called Knemidicoptes (if you want to make an effort at pronouncing this word the K is silent). We usually encounter this problem in parakeets (Budgies) at our hospital. This parasite causes extensive crusting and hair loss, fortunately it is readily treatable.

Cause

Scaley face disease is caused by a mite called Knemidicoptes that is spread from bird to bird by contact. Some birds acquire this parasite while young and do not develop symptoms until they are young adults.

Diagnosis

This disease is diagnosed by the character of the lesions and the fact that it has occurred in a Budgie. Microscopic examination by a skin scraping will reveal the mite.

This bird has the telltale lesions of scaley face mites. There is crusting on the neck and face, and a honeycombed appearance to the beak. This is a severe case. In addition, this bird has a growth on its beak.

Lesions also occur in other areas, most noticeably in the vent and on the feet.

Treatment

Years ago the only treatment we had was an ointment that was used to treat pubic lice in people. It was messy and had to be applied daily, but it usually worked. Now we use the drug Ivermectin, given every week or two until the problem is gone, usually within 3-4 weeks.

This is the same bird as above 10 days after its first Ivermectin treatment. We removed the growth on its head a few days before this.

Here he is 2 weeks after his second treatment. He is almost completely healed and feeling a million times better. Hard to believe its the same bird.

He was brought into our clinic and dropped off as part of our wildlife program since he was a stray and was found by one of our clients. He has a great personality, and once we got him looking like this we had no problem finding him a home (with a girlfriend).
